Indiana winters hit hard — and even one cold night can cause hundreds (or thousands) of dollars in freeze damage. That’s why we offer two professional winterization packages designed to protect your RV from freezing temperatures, busted pipes, leaks, and hidden cold-weather issues. Whether you want standard protection or full peace of mind, we’ve got an option that fits your needs.



A single freeze can burst pipes, crack fittings, damage tanks, destroy water heaters, flood slide floors, and lead to expensive spring repairs. Professional winterization protects your plumbing, appliances, roof, and seals — and gives you peace of mind all winter long.

Affordable, reliable, essential cold-weather protection.
Our Standard Winterization service prepares your RV’s entire water system for freezing temperatures and ensures everything is properly cleared and treated before winter hits.
Includes:
Perfect for RV owners who want dependable winter protection without the extras.

The most complete winterization service we offer — with guaranteed protection
Our Premier Winterization Package delivers complete cold-weather protection with a
full Freeze Guarantee. We guarantee your RV will NOT suffer freeze-related plumbing damage.
If it does? We cover the repairs.
This package includes everything from the Standard Winterization plus an expanded list of inspections and cleanings for total winter readiness, ensuring your RV stays safe all winter long or any springtime freeze-related plumbing repairs are on us.
The service includes draining both the water heater and freshwater tank, bypassing the water heater, thoroughly blowing out every water line with 50 PSI of compressed air, and circulating RV antifreeze throughout the plumbing system. We also perform a roof and exterior seal inspection—applying up to one full tube of sealant wherever needed to prevent water intrusion—along with cleaning both the furnace and AC unit to ensure smooth seasonal startup.
Tires are carefully inspected, house batteries are disconnected for proper winter storage, and we complete a detailed “point of intrusion” check to identify and address any areas where rodents could enter during the colder months.
This package is required for RVs equipped with an ice maker, washer/dryer, AquaHot, or Truma system due to their more complex winterization needs.

Yes. Indiana temperatures regularly drop below freezing, which can cause pipes, fittings, water pumps, and fixtures to crack. Winterization is the simplest and most affordable way to prevent expensive spring repairs.
Ideally, before the first hard freeze. In Indiana, most RVers schedule winterization between late September and early November. If temperatures are already dropping, the sooner the better.
Yes. You’ll want to flush the antifreeze, check seals, reconnect the battery, pressurize the water system, and inspect appliances. We offer de-winterization services to help you get road-ready again.
Our Standard Winterization covers the essential plumbing protection: draining tanks, bypassing the water heater, blowing out the lines, and adding antifreeze.
The Premier Winterization goes several steps further with a full-system care package—seal inspection (with sealant applied as needed), furnace and AC cleaning, tire inspection, battery disconnect, intrusion check, and our Freeze Guarantee, which means if something freezes, we fix it at no cost.
Only included in the Premier package, the Freeze Guarantee means that if your RV experiences any freeze-related plumbing damage after we winterize it, we take care of the repairs. No stress, no surprises, no extra charge.
Most winterizations take about an hour, depending on the RV and whether it includes items like washer/dryer units, ice makers, AquaHot, or Truma systems. Those require the Premier package, which includes more detailed work.
We do not recommend skipping antifreeze. Cold snaps, uneven heating, and trapped water pockets can still cause damage. Antifreeze adds an additional layer of protection—especially in harsh Midwest winters.

We bring reliable, high-quality mobile RV service right to your driveway, campsite, or storage lot. Wherever your RV is, we come to you.
Indiana winters don’t wait—so don’t leave your RV vulnerable. Secure your winterization now and avoid costly springtime surprises.
